In the black-and-white image, Anderson is rocking very curly hair and only wearing a pair of cat ears. "I found it liberating to use my body to make an important statement," the 49-year-old actress says of the ad. "People tend to look away from anti-fur ads showing mangled animals, but they're drawn to PETA's 'naked' campaign, and I'm proud to be a part of it."

Anderson isn't the first celebrity to strip down for the cause. Other stars to participate in the anti-fur campaign over the years include Pink and Taraji P. Henson.

This is not the first time Anderson has taken a stand for a cause she believes in. After news broke in June that The X-Files had reportedly hired an all-male team for the 11th season, the show's leading lady, who portrays Dana Scully, took to Twitter to share her opinion on the controversial decision.

"And two out of 207 eps directed by women," Anderson wrote in response to a story written by The Washington Post. "I too look forward to the day when the numbers are different. #TheFutureIsFemale."

Anderson hasn't been shy about advocating for women's equality in Hollywood. In a January 2016 interview with Vanity Fair, she also revealed that she was initially offered half of co-star David Duchovny's pay for The X-Files revival.
